两侧对称的

However, among zygomorphic Gesneriaceae species, some species have evolved from zygomorphy back to actinomorphy.

相较於辐射对称花，两侧对称花常具专一传粉者并有较高的授粉效率，故其种化速度亦常较前者来得快。

The metazoans in the Wenghui Biota had radiate symmetrical animals, including Porifera, Ctenophora, Cnidaria, and Trilobozoas, and bilateral symmetrical animals, including Annelida and possible Mollusca.

瓮会生物中宏体后生动物有海绵类、栉水母类、刺胞类和三叶类等两胚层辐射对称动物以及环节类和可能的软体类等三胚层两侧对称动物。

Bilaterally symmetrical, so that a line drawn through the middle of the structure along only one plane will produce a mirror image on either side.

左右对称的 Zygomorphous 两侧对称，仅在，通过结构中央仅有一个平面能将其分成互为镜像的两部分。

The second milestone was the development of bilateral symmetry ( two halves of the body mirror each other ) with an identifiable head , in contrast to radial symmetry ( symmetrical in a ray pattern from the center ), for example , jellyfish .

第二个重要事件是动物身体进化成两侧对称，并出现明显的头部组织。当然也有例外，例如海蜇这种生物就是径向对称（即对称点在身体中心，呈放射对称）。

Analysis of these mutations and cloning the corresponding loci will shield light on the underlying molecular mechanism in the control of floral asymmetry and facilitate our understanding on the evolution of the zygomorphic development.

对这些突变体的分析和基因克隆有助于阐明两侧对称花型发育的调控机制和理解两侧对称花型的进化途径。

Liverworts with bilaterally symmetrical gametophytes; sometimes placed in the order Jungermanniales.

具两侧对称的配子体的苔类的一科；有时包括在顶蒴苔纲的叶苔目中。

This design center simple chain about the scraper conveyer two sides are symmetrical, may install the reduction gear on two sidewalls, by left meets, the right mining coal working surface need.

此次设计的中单链型刮板输送机左右两侧对称，可以在两侧壁上安装减速器，以适应左、右采煤工作面的需要。

The normal mamillothalamic tracts and mamillary bodies were symmetric in size and signal intensity. The abnormal mamillary bodies were identified as asymmetric in size.

正常乳头丘脑束及乳头体两侧对称，信号均匀，与穹窿的信号一致；异常的乳头体表现为两侧不对称，一侧明显变小，并且乳头丘脑束显示不清。

The knock-down of the three LjCYC genes gives rise to the ventralized identity to all petals, which are keeled shape, resulting in a floral transformation from a zygomorphy to an asymmetry, indicating that the asymmetry floral pattern could be a ground stage before LjCYC1, LjCYC2 and LjCYC3 being recruited in the control of floral asymmetrical development in Lotus japonicus.

本实验得到了LjCYC1、LjCYC2和LjCYC3表达均下调的转基因株系L1+2Ri/kew1，该植株所有花瓣呈现腹部属性，出现了花瓣形态全是龙骨瓣状的非对称花瓣，花型也从两侧对称转化为无对称面；这种花型表明，在LjCYC1、LjCYC2和LjCYC3等三个基因全失活的情况下，龙骨瓣状花瓣应该是一个基准状态。

Flatfish, such as the flounder, are among the few vertebrates that lack approximate bilateral symmetry (symmetry in which structures to the left and right of the body's midline are mirror images).

鲆鱼，例如比目鱼，是少数左右两侧不太对称的脊椎动物之一（左右两侧对称指的是身体中线左右两边的结构为镜象反射）。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
